filter is very dirty, it can be washed in lukewarm water with
regular dishwashing detergent. Note that the fleece filter does
not need to be cleaned until there

a noticeable
loss
of power.
If cleaning the filter does not bring an improvement in
performance, it is time to replace it.

the inside with compressed air. If the filter is very dirty, it can be
